Protection switching surges

Protection of rotating machines from switching surges 17/578... [Pg.555]

The need to protect a rotating machine from switching surges, contact bouncing and surge transferences 17/576... [Pg.555]

These are only basic guidelines. It is difficult to define exposed or shielded equipment accurately. Equipment installed indoors may never be subject to lightning strikes or their transferences, but may be exposed to severe switching surges and require surge protection as for an exposed installation. There is no readymade formula by... [Pg.596]

A lightning surge protective level is found to be more stringent than the switching surge or FOW protective levels. Hence, it is sufficient to check the protective distance requirement for the lightning surge alone. [Pg.612]

Determining the severity of a transient Protection of rotating machines from switching surges Theory of surge protection (insulation coordination)... [Pg.997]

The principle equipment generally installed in a distribution substation are power transformers, oil or air circuit breakers, voltage regulators, protective relays, air break and disconnect switches, surge arresters, measuring instruments, and in some instances, storage batteries and capacitors. [Pg.1109]
